Description

Technical Field

[0001] This document relates to the field of electrical control, and in particular to a method, apparatus and storage medium for controlling a device. Background Technology

[0002] Currently, lifting and traversing mechanical equipment accounts for more than 90% of all mechanical equipment. Lifting and traversing mechanical equipment usually adopts a method of one programmable controller per set of equipment.

[0003] In the prior art, when the number of devices is large, the number of programmable controllers also increases accordingly, that is, the number of programmable controllers matches the number of devices.

[0004] In actual use, the controller is only needed during equipment operation. The equipment is mainly used for parking vehicles, and its operating time accounts for about 10%, with the majority of the time spent in a non-operational state. Therefore, in existing technologies, the controller is also in a long-term non-operational state, resulting in low utilization, high cost, and waste of resources and energy. Moreover, when the controller of a device malfunctions, the faulty controller needs to be removed and a new controller installed to restore the equipment to normal operation. Summary of the Invention

[0005] In view of the above analysis, this application aims to provide a control method, apparatus and storage medium for a device to solve at least one of the above-mentioned technical problems.

[0006] Firstly, one or more embodiments of this specification provide a method for controlling a device, including:

[0007] The number of PLC programmable logic controllers receiving external input, the number of devices to be controlled, and the percentage of average operating time of the devices to be controlled;

[0008] The expected waiting time of the devices to be controlled is determined based on the number of PLCs, the number of devices to be controlled, and the average running time percentage.

[0009] Match the corresponding number of PLCs according to the expected value.

[0010] Further, determining the expected waiting time of the controlled device based on the number of PLCs, the number of devices to be controlled, and the average operating time percentage includes:

[0011] The expected waiting time of the controlled device is calculated using the following formula:

[0012]

[0013] Where m represents the number of devices to be controlled, n represents the number of PLCs, p represents the percentage of average running time, and T represents the expected value of waiting time.

[0014] Further, determining the expected waiting time of the controlled device based on the number of PLCs, the number of devices to be controlled, and the average operating time percentage includes:

[0015] Determine the value ranges for the number of PLCs, the number of devices to be controlled, and the percentage of average running time, respectively;

[0016] Based on the range of values ​​and the formula, multiple expected values ​​are determined.

[0017] Further, matching a corresponding number of PLCs according to the expected value includes:

[0018] From the plurality of expected values, determine the smallest expected value;

[0019] Based on the minimum expected value, determine the corresponding number of PLCs and the number of devices to be controlled;

[0020] Based on the determined number of PLCs and the number of devices to be controlled, match the corresponding number of PLCs.

[0021] Furthermore, the method also includes:

[0022] Check for any faulty PLCs;

[0023] When a faulty PLC is present, the backup PLC is activated based on the number of PLCs corresponding to the expected value and the number of faulty PLCs.

[0024] Secondly, embodiments of this application provide a device control method apparatus, comprising a receiving module, a data processing module, and a control module;

[0025] The receiving module is used to receive external inputs of the number of PLC programmable logic controllers, the number of devices to be controlled, and the average operating time percentage of the devices to be controlled;

[0026] The data processing module is used to determine the expected waiting time of the devices to be controlled based on the number of PLCs, the number of devices to be controlled, and the average running time percentage.

[0027] The control module is used to match a corresponding number of PLCs according to the expected value.

[0028] Furthermore, the data processing module is used to calculate the expected waiting time of the device to be controlled using the following formula:

[0029]

[0030] Where m represents the number of devices to be controlled, n represents the number of PLCs, p represents the percentage of average running time, and T represents the expected value of waiting time.

[0031] Furthermore, the data processing module is used to determine the value ranges of the number of PLCs, the number of devices to be controlled, and the average running time percentage; and to determine multiple expected values ​​based on the value ranges and the formula.

[0032] Furthermore, the control module is used to determine the smallest expected value from the plurality of expected values; determine the corresponding number of PLCs and the number of devices to be controlled based on the smallest expected value; and match the corresponding number of PLCs based on the determined number of PLCs and the number of devices to be controlled.

[0033] Thirdly, embodiments of this application provide a storage medium for storing computer-executable instructions, which, when executed, implement the method described in any one of the first aspects.

[0034] Compared with the prior art, this application can achieve at least the following technical effects:

[0035] This application treats the average operating time percentage of equipment as a probability, thus transforming the solution for equipment waiting time into a solution for expected value. This allows for quantitative prediction of equipment waiting time, providing an intuitive basis for selecting the appropriate number of PLCs. Subsequently, based on the expected equipment waiting time, a corresponding number of PLCs are matched to reduce the number of PLCs and idle operating time, thereby improving efficiency, reducing costs, and saving energy. This application employs a method of multiple PLCs controlling multiple devices. When one PLC fails, the system can automatically connect another normally functioning PLC to control the device, solving the problem in the traditional method of one PLC controlling one device where a device cannot operate if the PLC of one device fails. Attached Figure Description

[0036] To more clearly illustrate the technical solutions in one or more embodiments of this specification or in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this specification. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0037] Figure 1 This is a flowchart illustrating a device control method provided for one or more embodiments of this specification. Detailed Implementation

[0038] To enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this document.

[0039] The reason why existing technologies use a one-to-one correspondence between the controlled device and the PLC is as follows:

[0040] 1. In real-world scenarios, the number of devices to be controlled and PLCs is often large, resulting in complex combinations of these devices and PLCs. Therefore, adopting a one-to-one correspondence between the controlled devices and PLCs can save time in handling complex situations.

[0041] 2. In real-world scenarios, the start-up time and working time of the devices to be controlled are uncertain, making it difficult to determine the waiting time of each device in advance.

[0042] To address the above scenario, this application provides a device control method, comprising the following steps:

[0043] Step 1: Receive external inputs for the number of PLCs, the number of devices to be controlled, and the percentage of average running time of the devices to be controlled.

[0044] In this embodiment, the average operating time percentage of the controlled device is the ratio of the device's working time to the total time during a specific period. For example, if the device works for 1 hour between 6 PM and 8 PM, then the average operating time percentage of the controlled device is 0.5. The number of PLCs, the number of controlled devices, and the average operating time percentage of the controlled devices can be a specific number or a range of values.

[0045] Step 2: Determine the expected waiting time of the devices to be controlled based on the number of PLCs, the number of devices to be controlled, and the average running time percentage.

[0046] In this embodiment, since the proportion of the average operating time of the device to be controlled is dimensionless, the proportion of the average operating time is treated as a probability to facilitate the quantification of the waiting time of the device to be processed. The formula for calculating the expected value of the waiting time of the device to be controlled is as follows:

[0047]

[0048] Where m represents the number of devices to be controlled, n represents the number of PLCs, p represents the percentage of average running time, and T represents the expected waiting time. It should be noted that i-n+1 represents the number of cycles. One cycle is the duration of the PLC's operating state during one control cycle.

[0049] In this application embodiment, there are two scenarios for calculating the expected waiting time:

[0050] Scene 1

[0051] The user determines the number of PLCs, the number of devices to be controlled, and the average uptime percentage. For example, if the user decides to use 3 PLCs to control 5 devices and the average uptime percentage is 0.8, only the device waiting time needs to be calculated. In this case, simply input the above parameters into the formula.

[0052] Scene 2

[0053] The user is unsure of the number of PLCs, the number of devices to be controlled, and the percentage of average running time. For example, the user may not know how many PLCs to select to control the devices, nor how many devices to select to reduce waiting time. In this case, the user can input a range of values ​​for one or more of the following: the number of PLCs, the number of devices to be controlled, and the percentage of average running time. Accordingly, the program in this application determines the range of values ​​for the number of PLCs, the number of devices to be controlled, and the percentage of average running time; based on the range of values ​​and the formula, multiple expected values ​​are determined.

[0054] For example, if the user inputs the number of PLCs: 1-3, the number of devices to be controlled: 5, and the average running time percentage: 8; the calculation result using the aforementioned formula is:

[0055] When using 3 controllers, T = 1.065 ≈ 1 equipment operation cycle. That is, for 5 sets of mechanical parking equipment, using 3 controllers will increase the waiting time of the 5 sets of equipment by about 1 equipment operation cycle during peak hours.

[0056] When two controllers are used, T = 2.007 ≈ 2 equipment operation cycles. That is, for 5 sets of mechanical parking equipment, using two controllers will increase the waiting time of the 5 sets of equipment by about 2 equipment operation cycles during peak hours.

[0057] When using one controller, T = 3.000 ≈ 3 equipment operation cycles. That is, for 5 sets of mechanical parking equipment, using one controller will increase the waiting time of the 5 sets of equipment by about 3 equipment operation cycles during peak hours.

[0058] Step 3: Match the corresponding number of PLCs according to the expected value.

[0059] In this embodiment, for scenario 1, if the user is not satisfied with the expected value, the number of PLCs, the number of devices to be controlled, and the average running time percentage can be adjusted. Then, the aforementioned formula is used to recalculate until the user's requirements are met. Finally, the appropriate number of PLCs is matched according to the corresponding expected value.

[0060] For scenario 2, the minimum expected value is determined from multiple expected values; based on the minimum expected value, the corresponding number of PLCs and the number of devices to be controlled are determined; and based on the determined number of PLCs and the number of devices to be controlled, the appropriate number of PLCs are matched. Furthermore, users can select the appropriate expected value based on actual needs, and this expected value does not necessarily have to be the minimum. For example, in the example of step 2, the user can choose to match 2 PLCs after comprehensively considering cost and efficiency.

[0061] In the existing technology, to ensure equipment operation in the event of a PLC failure, users typically need to prepare some spare PLCs. Based on the above scenario, to maintain work efficiency, it is necessary to replace the faulty PLC promptly. In this embodiment, the system detects the presence of a faulty PLC; when a faulty PLC is found, it automatically connects to another normally functioning PLC, thus maintaining normal equipment operation without replacing the PLC. For example, if three PLCs are currently operating, and one PLC suddenly fails, to ensure work efficiency, one of the two normally functioning PLCs is automatically connected.

[0062] This application provides a device control method apparatus, including: a receiving module, a data processing module, and a control module;

[0063] The receiving module is used to receive external inputs of the number of PLC programmable logic controllers, the number of devices to be controlled, and the average operating time percentage of the devices to be controlled;

[0064] The data processing module is used to determine the expected waiting time of the devices to be controlled based on the number of PLCs, the number of devices to be controlled, and the average running time percentage.

[0065] The control module is used to match a corresponding number of PLCs according to the expected value.

[0066] In this embodiment of the application, the data processing module is used to calculate the expected waiting time of the device to be controlled using the following formula:

[0067]

[0068] Where m represents the number of devices to be controlled, n represents the number of PLCs, p represents the percentage of average running time, and T represents the expected value of waiting time.

[0069] In this embodiment of the application, the data processing module is used to determine the value ranges of the number of PLCs, the number of devices to be controlled, and the average running time percentage; and to determine multiple expected values ​​based on the value ranges and the formula.

[0070] In this embodiment of the application, the control module is used to determine the smallest expected value from the plurality of expected values; determine the corresponding number of PLCs and the number of devices to be controlled based on the smallest expected value; and match the corresponding number of PLCs based on the determined number of PLCs and the number of devices to be controlled.

[0071] This application provides a storage medium for storing computer-executable instructions, which, when executed, implement the methods described in any of the above embodiments.

[0072] The foregoing has described specific embodiments of this specification. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims may be performed in a different order than that shown in the embodiments and may still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require the specific or sequential order shown to achieve the desired result. In some embodiments, multitasking and parallel processing are possible or may be advantageous.

[0073] In the 1930s, improvements to a technology could be clearly distinguished as either hardware improvements (e.g., improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the methodology). However, with technological advancements, many improvements to the methodology today can be considered direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved methodology into the hardware circuit. Therefore, it cannot be said that an improvement to the methodology cannot be implemented using a hardware physical module. For example, a Programmable Logic Device (PLD) (e.g., a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by the user programming the device. Designers can program a digital system themselves to "integrate" it onto a PLD, without needing chip manufacturers to design and manufacture dedicated integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing integrated circuit chips, this programming is mostly implemented using "logic compiler" software. Similar to the software compiler used in program development, the original code before compilation must be written in a specific programming language, called a Hardware Description Language (HDL). There are many HDLs, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, and RHDL (Ruby Hardware Description Language). Currently, the most commonly used are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should understand that by simply performing some logic programming on the method flow using one of these hardware description languages ​​and programming it into an integrated circuit, the hardware circuit implementing the logical method flow can be easily obtained.

[0074] The controller can be implemented in any suitable manner. For example, it can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicon Labs C8051F320. A memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also recognize that, in addition to implementing the controller in purely computer-readable program code form, the same functionality can be achieved by logically programming the method steps to make the controller take the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers. Therefore, such a controller can be considered a hardware component, and the means included therein for implementing various functions can also be considered as structures within the hardware component. Alternatively, the means for implementing various functions can be considered as both software modules implementing the method and structures within the hardware component.
